Molluscum contagiosum is an infection of the skin.

Diagnosis is usually made based on the lesion appearance. Sometimes a biopsy will be taken to rule out other conditions. A biopsy is the removal of a small sample of the area.
Molluscum contagiosum usually goes away on its own within six months to two years without any treatment. For people with HIV infection, the lesions usually persist and spread indefinitely. Your doctor may recommend the removal of some lesions to prevent the spread of the infection or to avoid infecting others.
Lesion may be removed by one of the following: Cryotherapy—freezing of the lesionCurettage—cutting out lesionLaser surgery—steady or pulsed high intensity lightTopical therapy—destruction of the lesion with a variety of chemicals
To reduce your chances of getting molluscum contagiosum, avoid any contact with an infected person.
If you are contagious, avoid any personal contact with others, contact sports, or sharing personal items.
